Drill bit for metal MODECO MN-60-320 HSS cylindrical 12 mm set of 10

Set of 10 MODECO MN-60-320 HSS cylindrical drill bits, diameter 12 mm, designed for drilling metal. Manufactured from high-speed steel (HSS) for improved hardness and heat resistance, this set is intended for creating precise through-holes in steel and other ferrous and non-ferrous metals. The cylindrical shank fits standard chucks and drilling machines used in workshops and construction sites. The set of ten identical bits provides spare tools for repeated tasks or replacement when a bit becomes worn.

Advantages

The HSS material ensures wear resistance and sustained cutting performance at elevated temperatures during continuous drilling. A consistent 12 mm diameter across the set allows predictable hole sizes and simplifies tool selection. The cylindrical shank provides compatibility with a wide range of drills and chucks, and the uniform set packaging supports efficient inventory management for maintenance or production environments.

Suitable for

• Drilling through mild steel, stainless steel, and other common metals
• Workshop and maintenance tasks requiring repeatable 12 mm holes
• Construction and metal fabrication where standard shank bits are needed
• General metalworking, repairs, and mechanical assembly

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 12 mm
• Shank type: cylindrical (straight) shank compatible with standard chucks
• Quantity in set: 10 pieces
• Intended use: through-holes in metal

How to use

Select a drill or drill press with a chuck that accepts cylindrical shanks and secure the 12 mm bit firmly in the chuck. Mark and center-punch the drilling point on the workpiece to reduce wandering. Use appropriate cutting speed and feed for the metal being drilled: moderate speeds and steady pressure for stainless steel, higher speeds for softer steels, combined with cutting fluid or coolant to reduce heat and prolong bit life. Clear chips frequently and back the bit out occasionally when drilling deep holes to remove swarf.

Usage recommendations

For best results, use cutting fluid when drilling harder alloys, and avoid excessive speed to prevent premature wear. Store the set in a dry place and inspect bits for bluntness or chipping before use; replace damaged bits to maintain drilling accuracy and safety.
